Assessing Lean performance
The Lean metrics identified so far help us evaluate the efficiencies of flow across our value streams and act as a means to identify areas of waste. But we also need methods to assess the areas that require the most attention in order to eliminate waste as part of our ongoing Kaizen efforts. A practical way to do this is by developing a Lean assessment radar chart.
The Lean assessment radar chart maps specific Lean objectives that you've already learned to a grid, radiating outward like spokes from a central hub. A completed radar chart looks a bit like a spider's web, as depicted in Figure 8.3. This figure contains a graphical display of an example Lean assessment radar chart:

A radar chart implements scales to rank capabilities ranging from no commitments at the center of the hub to a level representing world-class capabilities at the outer radius. The example in Appendix...
